Struct weld::WeldError

pub struct WeldError { /* fields omitted */ }

An error when compiling or running a Weld program.

Methods

impl WeldError

pub fn new<T: Into<Vec<u8>>>(message: T, code: WeldRuntimeErrno) -> WeldError

Creates a new error with a message and error code.

Examples

use weld::{WeldError, WeldRuntimeErrno};

let err = WeldError::new("A new error", WeldRuntimeErrno::Unknown);

pub fn new_unknown<T: Into<Vec<u8>>>(message: T) -> WeldError

Creates a new error with a particular message and an Unknown error code.

Examples

use weld::{WeldError, WeldRuntimeErrno};

let err = WeldError::new_unknown("A new unknown error");
assert_eq!(err.code(), WeldRuntimeErrno::Unknown);

pub fn new_success() -> WeldError

Creates a new error with a particular message indicating success.

The error returned by this function has a message "Success" and the error code WeldRuntimeErrno::Success.

Examples

use weld::{WeldError, WeldRuntimeErrno};

let err = WeldError::new_success();
assert_eq!(err.code(), WeldRuntimeErrno::Success);
assert_eq!(err.message().to_str().unwrap(), "Success");

pub fn code(&self) -> WeldRuntimeErrno

Returns the error code of this WeldError.

Examples

use weld::{WeldError, WeldRuntimeErrno};

let err = WeldError::new("An out of memory error", WeldRuntimeErrno::OutOfMemory);
assert_eq!(err.code(), WeldRuntimeErrno::OutOfMemory);

pub fn message(&self) -> &CStr

Returns the error message of this WeldError.

Examples

use weld::{WeldError, WeldRuntimeErrno};

let err = WeldError::new("Custom error", WeldRuntimeErrno::Unknown);
assert_eq!(err.message().to_str().unwrap(), "Custom error");
